Quintessence inhomogeneous cosmology
The Einstein–Klein–Gordon field equations are solved in a inhomogeneous shear–free universe containing a material fluid, a self–interacting scalar field, a variable cosmological term, and a heat flux. A quintessence– dominated scenario arises with a power–law accelerated expansion compatible with the currently observed homogeneous universe.
متن کاملNeutrino Lumps in Quintessence Cosmology
Neutrinos interacting with the quintessence field can trigger the accelerated expansion of the Universe. In such models with a growing neutrino mass the homogeneous cosmological solution is often unstable to perturbations. We present static, spherically symmetric solutions of the Einstein equations in the same models. They describe astophysical objects composed of neutrinos, held together by gr...
متن کاملAngular size in “ quintessence ” cosmology
We investigate the influence of an exotic fluid component (" quintessence ") on the angular size-redshift relation for distant extragalactic sources. Particular emphasis is given for the redshif z m at which the angular size takes its minimal value. We derive an analytical closed form which determines how z m depends on the parameter of the equation of state describing the exotic component. The...
متن کاملQuintessence Cosmology and the Cosmic Coincidence
Within present constraints on the observed smooth energy and its equation of state parameter wQ = P/ρQ, it is important to find out whether the smooth energy is static (cosmological constant) or dynamic (quintessence). The most dynamical quintessence fields observationally allowed are now still fast-rolling and no longer satisfy the tracker approximation if the equation of state parameter varie...
متن کاملVarying Constants, Gravitation and Cosmology
Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would reflect the existence of an almost massless field that couples to matter. This will induce a violation of the universality of free fall. Thus, it is of utmost importance for our understanding of gravity and of the domain of validity of general relativity to test for their constancy. We ...
